DawgTalkers.net Forums DawgTalk Everything Else... Eclipse?

I can't believe that I'm the first to post about this upcoming event.

I'm one of the lucky ones. The moon's shadow will pass directly across my property.

It's possible that I may be able to experience this last-in-my-lifetime phenomenon from my back yard. If my neighbor's trees interfere with a clear view, we can walk the distance of one city block to a tucked-away, yet wide-open area that only we neighbors know about (I live in one of the coolest Central City metropolitan neighborhoods in America-).

Any other Dawgs nerdy enough to be in on this event/phenomenon... one which will not happen for another 20 years?

Speaking only for myself, this is the s#.
I've been a surface-level fan of science/astronomy since my elementary school days.

This thing is happening right over my rooftop.
You can bet your last dollar I won't miss this.


Any other "Totality Dawgs" planning to experience this once-in-a-lifetime event?
What are your plans?

This is the place for all things eclipse/celestial
Join in, nerds!

Totality passes over my childhood home. My mom and sister still live in the property. Wish I could be there with them to look up.
I got lucky last go, a few years back. Totality was a drive over the mountains an hour or so away. Got to see it rhat time.

Enjoy your view.

I plan on being grocery shopping. Stores should be empty.

As have you, astronomy has gripped me ever since I got a cheapo Jason(?) refractor for Christmas when I was maybe 9-10 years old. I have had 4 upgrades since then...lol.

My wife and I are heading out in 3 hours or so to spend the night in Cincy, then truck on to Medina to hunker down until we return on Tuesday. Just pull out the folding chairs and watch from the parking lot of the hotel. I have stayed at that exit several times when going to Browns games so I know the sky is in full view. I will situate the car in such a manner where we can sit in the car and watch, getting out when totality is near if it's windy and cold.

We had one here maybe 10-15 years ago? Not total, but it was maybe 90%. One of the cool aspects of this is to watch and listen to the wildlife. It's early for crickets, but they started chirping as it became dusk. The birds start singing their night songs from the treetops. I probably won't get much of that in my location, but from what you describe, you probably will.

As you said, the next one anywhere close is in 20 years so this is a last in a lifetime event for me. I am pretty sure I won't be around in 20 years, and if by fluke I am, I will probably be in some nursing home.

On a side note, a rare event takes place later this month or maybe May in your area. Cicadas by the billions will emerge. Both the 13 year and 17 year broods will emerge at the same time. Something that last happened in 1803. Rare indeed. Get ready for a lot of noise rumbling from the trees.

Same neck of the woods.....about a minute and a half of totality for us. I'll be working from home and my wife will be here. We're going to watch together, and our backyard is a great place to view from. I hope the clouds stay away....the forecast is looking better than earlier predictions.

I was just thinking the same when driving back to OH last night for this event, "I wonder why no one has mentioned this on DT?".

Then I realized I'm as guilty as everyone else. 🤣 I've been driving my family crazy for about a year. Bought a 25 pack and handed out glasses to everyone in the fam at Christmas. "What eclipse??"


I've been preparing for this event since the '70s. I remember going through a list of eclipse events in an encyclopedia and being shocked to see the path in "2024". I remember thinking "I'll be an old man by then" lol. I told a close friend in high school about it, had to go to the library to look it up:

"Yep, but we'll be 57 bro, you think we'll still be hanging out?"
"Who knows, we'll be old!", I said.
"If we are, we'll have to plug Dark Side of the Moon in the tape deck."

He's gone. I'll listen to Dark Side in his honor.


About two minutes of totality here. Pretty damned excited.

Have some GI tests the next day, so I imagine I will be indisposed during the eclipse. Get to go off solid food for a bit starting tomorrow.

Put a bucket in the yard -- it will be dark anyway!

Brother and sis in law are coming from Colorado today for this reason. Staying with us til Tuesday. They're heading down to the Lima or Findlay area to get a better effect.

And peen, speaking of cicadas: 17 years ago right around this time we went to Indy for a wedding. The cicadas were so loud it was crazy. Even driving with the windows up we could hear them.

Just wait until this spring/ summer.......

A Double Emergence of Periodical Cicadas Isn’t Cicada-geddon—It’s a Marvel

The U.S. will see two adjacent broods of periodical cicadas emerge this spring

https://www.scientificamerican.com/article/a-double-brood-of-periodical-cicadas-will-emerge-in-2024/

Iwill try to watch it. I saw the last one. Pretty bad ass.

It was probably about 20 years ago that I read an article about Cicadas and was blown away at the fact that their population cycles are spans that are always prime numbers -- in order to promote their proliferation and survival. In other words, the two broods that will emerge this year are ones of 13-year-cycles and 17-year-cycles, so they only exist 'together' once every 221 years! Crazy that millions of years of DNA taught them to 'understand math'.

The Cicada’s Love Affair With Prime Numbers

Even though I can see it from my backyard I will be driving to my son’s place in Westlake where it is almost dead center

Eclipse map that will allow you to pinpoint exact times (beginning, totality start/end, ending) for your precise location.

Thanks. It's cool to scroll out a see a simulation of the shadow as it moves NE.

Also, in case anybody is confused. The times shown are set for UTC time, which is 4 hours ahead of us here in eastern daylight savings time.

I am in Medina looking out the window of the hotel hoping everybody is correct and this low cloud deck moves on out. The rain stopped around 5-6am which was predicted so there is no reason to think the clouds won't move out around noonish as predicted.

Hope everybody dodges the clouds and at least gets a decent view.

We're bright and sunny here in NW OH, so it should clear up for you shortly.

A few stray clouds in Warren, they've been moving in and out.

I put the glasses on when the sun was hidden behind 'thin' clouds and could see the sun loud and clear -- just also saw the clouds moving in front of it.

Unless we have some dense clouds move in at the wrong time, this should be great.

Can I just squint really quickly and take a fast look when it's a total eclipse or is even that dangerous?

It's clear out now, but in a couple hours it's supposed to be partly cloudy (sighs).

You shouldn't look at it. Your eyeballs don't have nerves in them so you can damage them without even feeling pain.

Jc

Started at 2pm. It’s 2:07 right now here in NE Ohio and the clouds rolled in

If really quickly means how long you can look at the sun any other day, sure. Just understand that is a blink of the eye.

You can stare right into the sun during totality.

We had clouds earlier, but they left. I can see it. We will get 84% totality here. It's well on the way.

Clouds don't matter if you can see a shadow......

Plan on setting up outside around 2:30.

I went right on my balcony and saw it. That was pretty darn incredible!

Really glad the family got to see this!!! Crazy how dark everything got!! All the insects came out and was chirping!

Great visibility here in Aurora Ohio.

Weird......

Not a bird in the sky.

No doubt an impressive moment. I knew the birds would do their deal singing their night songs before getting quiet. I wasn't sure if the crickets would be out this early up here, but they started chirping.

Had great viewing here in Medina. Light clouds, but as long as you get a shadow, you can see the sun. It was great.

It's never a wasted trip when my wife and I head out somewhere, but it would have been disappointing had it been thick cloud cover.

A perfect get away. Spending the night in Lexington, KY. tomorrow. My days of making the 10 hour drive straight through are done. Get about 60% of the drive in tomorrow and leave 4 or so hours on Wednesday.

If anyone got some good pictures, please post 'em here. Mine look like crap/not worth sharing.

Well, that was definitely worth it. Near perfect weather in Warren, Ohio. Never a time when the scant clouds impeded the view. 90% of the two hours, no clouds in front of the sun at all. I was pretty worried up until about 1pm.

Getting close to totality, the scene seemed to drag in a little haze behind it. I was a little concerned at how it may affect the ring of fire, it had no bearing, all was crystal clear. What an amazing experience!

As we got close to totality the temp seemed to drop dramatically. We've got woods right across from our house, it was at this time all the birds began to gather there rather than surrounding us as they were beforehand. Almost like a roll call and a "what the heck is going on guys??" lol Much louder. Then the alarmed voices changed to song as totality set across the horizon.

I expected it to be much darker. Some of these scientists that past week were over the top and way off in that respect.


I ripped my glasses off and my son lost his marbles; "what are you doing??". I told him to take his off and look.. "I'm scared! Are you sure??" 🤣

We were a little freaked out by the red dot at the bottom of the ring. It was pronounced and I had no idea what to think of it. I found this later:



That was worth the decades of waiting.



My pics look more like a donut in the sky, my wife's are much better:









And seriously. How cute is this dawgie?? 🤩

The MIL's pooch, Tito, was also mesmerized by the eclipse.

I tried to spot the devils comet that is trailing the sun at this point but couldn't see it. I did see Venus which is a morning planet at this point. It was pretty cool seeing it a 3:15 in the afternoon.

We attended a gathering at a friend's family farm (approx 40 minutes from S/SW from our home) that afforded us 2.5 min of totality.

It was a trip to see hear the ambient natural noise quiet, and watch the birds fly home to roost, high up in the trees.
At totality, I took off my specs, looked around, and saw the same purple/orange sky one would expect at dusk. Jim had built a campfire, well in advance of The Event. As the ambient temp began to drop, all partiers gravitated to the fire ring. It was like so many campfires I'd attended over decades... but it happened within a 5-minute span of time- in the middle of the afternoon.

At one point during Totality, I took off my specs to look around.
It was a deep twilight version of what I'd seen just moments before. It truly felt like dusk/twilight- in a place that we've known well for more than 20 years- at all hours of the day/night.

Totally disorienting/mind-bending. The hairs on my arms stood at attention for at least 2-3 minutes. Even armed with the knowledge of hundreds of years of scientific background behind this phenomenon, I must admit: this event freaked me out, on a metaphysical level, and made me feel small- faced with the enormity of space, time, Earth's existence... and my miniscule place in the timeline that owns us all.

It's easy to understand how primitives who experienced this phenomenon thought that The World was somehow changed/coming to an end.

Just before Me & My Hunny left the party, I called all attendees together. We all joined hands in a circle, and raised them to the sky.
Clemmy: "Eclipse- on three: ...one, two, three... ECLIPSE !!!"

When we finished that st00pit little ceremony of mine, we all locked eyes for a brief moment... and recognized that we'd communally experienced something that we'd never all share again.
It changed us all.


Until Death or Alzheimer's takes away my brain, I will never forget where/when I was, when I experienced this moment.

Venus was easy to see. Brighter than s#, she was.
I also pointed out Orion's Belt to anyone who was interested.


"Space Nerd's Holiday," to be sure.

My sister took some beautiful photos. Said it really was an amazing experience to share with her kids and one of her grandkids.
My little brother said his son got teary eyed and his oft jaded daughter was awe struck.
So happy my family all got to experience such an event from their backyards. When you’re poor, having the entertainment come to you is nice. Thanks universe for providing for my family.

Great share, Portland.

I wish you could have been present/local to experience it with all of us.
Of all the Dawgs I've met at this place, I can't imagine anyone who would have enjoyed it more.

I would have liked to have just been home with my family. Eclipse or not. That would have filled my bucket.

Blaze Star: Huge stellar explosion will be visible from Earth for a week in once-in-a-lifetime event

ByEric Ralls, Earth.com staff writer

For the first time in eight decades, a celestial phenomenon will grace our night sky, offering a once-in-a-lifetime chance to witness a star’s brilliance with the naked eye during a dramatic explosion.

Known as T Coronae Borealis, or T CrB, this star resides 3,000 light-years from Earth in the Northern hemisphere’s expanse and is on the brink of an intense outburst.

Star explosion in the Corona Borealis constellation
This event, set to occur this year, will see T CrB lighting up the Corona Borealis constellation, shining as brightly as the famed North Star, Polaris, for approximately one week.

Corona Borealis, also known as the Northern Crown, is a small constellation located in the northern celestial hemisphere. It contains a semicircular arc of stars that resemble a crown.

The brightest star in the constellation is called Alphecca or Gemma, which is an eclipsing binary star system.

T CrB, the recurring nova located within the Corona Borealis constellation, consists of a white dwarf and a red giant star orbiting each other closely. The white dwarf siphons matter from the red giant, causing occasional outbursts that significantly increase the system’s brightness.

T CrB is nestled within the Corona Borealis constellation, lying in a semicircular pattern between the Bootes and Hercules constellations.

The exact timing of this stellar spectacle remains uncertain, with NASA forecasting its occurrence sometime between now and September.

The imminent outburst, classified as a nova, represents a rare astronomical event that unfolds roughly every century.

It happens when a white dwarf star — comparable in size to the sun but collapsed – and a red giant star — nearing the end of its life and expanding to about 74 times the sun’s size – venture too close to each other.

This proximity dramatically raises the red giant’s surface temperature from about 4,000 to 5,800 degrees Fahrenheit to an astonishing 360,000 degrees Fahrenheit, prompting T CrB to expel its outer layers onto the white dwarf’s surface.

Enormous thermonuclear explosion
The culmination of matter from the red giant triggers a nuclear explosion, unleashing an energy burst up to 100,000 times greater than the sun’s annual output.

Unlike a supernova, which obliterates the star, a nova such as T CrB’s does not destroy the star system. Instead, the star cools down to its original temperature and restarts its cycle.

Historical records trace T CrB’s notable eruptions back to 1946 and even 1866, with earlier accounts suggesting observations several centuries ago.

Notably, Reverend Francis Wollaston in 1787 and Abbott Burchard in 1217 documented witnessing a bright star in the Corona Borealis constellation, hinting at earlier appearances of T CrB.

Brief yet intense display
This particular star explosion is unique for its brief yet intense display, completing its cycle in merely a week.

NASA anticipates that the nova’s peak brightness will allow it to be visible to the naked eye for several days, and with binoculars for just over a week, before it fades away, potentially not to reappear for another 80 years.

This upcoming event invites sky enthusiasts and the curious alike to marvel at the wonders of our universe, showcasing the ephemeral yet awe-inspiring nature of celestial phenomena.

More about T Coronae Borealis (T CrB)
As discussed above, T Coronae Borealis (T CrB), often termed the ‘Blaze Star,’ is a captivating binary star system located in the constellation Corona Borealis.

This astronomical wonder stands out due to its explosive behavior — it’s a recurrent nova system. Comprising a red giant and a white dwarf, T Coronae Borealis periodically lights up the night sky with its dramatic outbursts.

The phenomenon occurs when the white dwarf, a dense remnant of a star that has exhausted its nuclear fuel, draws material from its companion red giant.

As this material accumulates on the white dwarf’s surface, it eventually triggers a thermonuclear explosion. This process causes the system to dramatically increase in brightness, making it visible even to observers on Earth with the naked eye.


Enigmatic white dwarfs
Central to the spectacle of T Coronae Borealis is the white dwarf, a stellar remnant that offers profound insights into the life cycles of stars.

White dwarfs are the end products of stars that originally had masses up to eight times that of the Sun but ended their lives in a relatively peaceful manner, without exploding as supernovae.

These stellar cores are fascinating for several reasons:

Density and Composition: Despite their diminutive size, white dwarfs are incredibly dense. Their mass is comparable to that of the Sun, but they have a volume similar to Earth’s. This high density arises because the matter within them is in a degenerate state, where electrons are packed closely together.

Cooling Process: After their formation, white dwarfs embark on a long cooling process. They start out extremely hot but gradually radiate away their heat over billions of years, eventually fading into black dwarfs — theoretical objects that have not yet been observed because the universe is not old enough.
Limiting Mass: The Chandrasekhar limit, approximately 1.4 times the mass of the Sun, defines the maximum mass a white dwarf can have. Beyond this limit, the star would collapse under its own gravity to form a neutron star or a black hole.

Window into cosmic evolution
In summary, the study of T Coronae Borealis and white dwarfs opens a window into the complex processes governing stellar evolution.

By observing these celestial phenomena, scientists gain valuable insights into the life cycles of stars, the dynamics of binary star systems, and the ultimate fate of our own Sun.

As observers on Earth, witnessing the dramatic eruptions of T Coronae Borealis or understanding the nature of white dwarfs connects us more deeply with the cosmos.

These celestial events and objects remind us of the dynamic universe we inhabit, where stars are born, live out their lives, and meet their end in spectacular fashion.

Differences between nova and supernova explosions
The cosmos is a stage for some of the most spectacular and powerful events known to science. Among these, nova and supernova explosions stand out for their brilliance and the fundamental roles they play in the universe’s lifecycle.

Despite the similarity in their names, novae and supernovae differ vastly in their origins, mechanisms, and consequences. This article demystifies these cosmic phenomena, highlighting their distinct characteristics.

As discussed above, a nova occurs in a binary star system, where a white dwarf and a companion star orbit closely. The white dwarf, a dense remnant of a star that has exhausted its nuclear fuel, pulls material — primarily hydrogen — from its companion.

This material accumulates on the white dwarf’s surface, eventually igniting in a thermonuclear explosion. The explosion causes the white dwarf to brighten significantly, but it does not result in the star’s destruction. Instead, the process may repeat if the white dwarf continues to accrete material.

What is a supernova?
In contrast, a supernova is a cataclysmic event marking the death of a star. Supernovae can occur in one of two primary ways:

Core-Collapse Supernova: This type happens at the end of a massive star’s life cycle. When the star’s core runs out of nuclear fuel, it can no longer support the outer layers against gravity. The core collapses, resulting in a massive explosion that obliterates the star.

Type Ia Supernova: This type involves a binary system where a white dwarf accretes material from a companion star, similar to a nova. However, in this case, the white dwarf reaches a critical mass (Chandrasekhar limit), leading to a runaway nuclear reaction that completely destroys the white dwarf.

Key differences between novae and supernovae
Scale and Energy
The most striking difference lies in their scale and the energy released. Supernovae are among the universe’s most energetic events, outshining entire galaxies and releasing vast amounts of energy. Novae, while still bright and powerful, are far less energetic and only cause a temporary increase in brightness.

Frequency and Visibility
Supernovae are relatively rare events, occurring about once every 50 years in a galaxy the size of the Milky Way. Novae, on the other hand, are more common, with several occurring in our galaxy each year. Despite their rarity, supernovae can often be seen from greater distances due to their immense brightness.

Outcome
A supernova marks the end of a star’s life, often leaving behind a neutron star or black hole. The explosion disperses the star’s material into space, contributing to the cosmos’s chemical enrichment.

A nova does not destroy the white dwarf. Instead, it merely expels the outer layers of accumulated material, allowing the process to potentially repeat.

Contribution to the Cosmos
Both phenomena play significant roles in the cosmic lifecycle. Supernovae are crucial for distributing elements necessary for life throughout the universe, while novae contribute to the understanding of stellar processes and the dynamics of binary star systems.


In summary, though novae and supernovae might be mistaken for similar phenomena due to their names and explosive nature, they are fundamentally different in their origins, mechanisms, and implications for the cosmos. Understanding these differences enriches our knowledge of the universe and underscores the vast and varied processes that govern the lifecycle of stars.
